Had I not torn it open quickly it probably would have been much worse. Fortunately, the battery seems to be fine. I’ll replace the charge and discharge cables to be safe along with the BMS.
I’m undecided on ESC replacement… there are some interesting new options to consider now.
I was sure to order those too. 
Chuck the flipsky antispark. That was what drained one of my packs and had an issue where after turning it off via button, the battery indicator takes about 5 seconds to turn off, whereas it would normally shut off a second after the button.
Any recommendations? I was following some promising options but will add an anti spark key regardless of what I use.
And speaking of which, great write-up on the loop keys.
Was this the newest Smart Enhanced one?
So far the most reliable antispark switch that I’ve used besides the loop key is the one from Lunacycle. Its 39 US from their site if I remember correctly. Sorry but I’m on mobile so I cant link it
Nope, it’s their cheaper model, and I got it back in mid 2018
Oh, good. Because I’m really happy with the new one. Thanks!
Yep that’s the one. I use this switch on three builds, none have failed…yet 
I’ve used a few of these myself. All of them have failed eventually, although most lasted a good while. In fact I had one, from an experimental batch that Luna sent me, that lasted almost 2 years.
What 'n tornation
(EDIT: my bad @agentdev didnt realise i was derailing, in an effort to stay on topic, really cool build. I really like the scheme and your commitment to the name)
All good! And what on earth happened there 
@physicsman99 may or may not be able to figure out why that happened. Or maybe it’s too exploded to tell now. He does some cool internal imaging for electronics with all kinds of xray/ultrasound things
Wow. I like the board, but not necessarily what you’ve done with the ESC. I don’t they they are supposed to look like that…
Are there any devices on the board which are obviously blown or cracked?@BluPenguin is correct. I work in/run a lab with ultrasonic inspection tools, and normally an x-ray machine close by. Not the medical ones, but the non-destructive testing kind.
@BluPenguin sent me a failed board from a board of his and I have found two FETs which wouldn’t pass a QC screening inspection. That’s two out of 24. Optical inspection is three diodes have failed,one of which was blown off of the PCB completely. I wouldn’t mind to check it out for interests sake in seeing what may have gone wrong.

The Enterprise has returned! The 183/185 KV motors (measured by VESC tool) and 13:43 gearing with AVIO Drive gets me a cruising speed of 35 MPH on Bergmeisters.
The 15-tooth pinions are on my bench… for now.
Which ESC did you end up switching to?
